Hello folks!

I have some problems with ash and msh shells while trying to build a 
statically linked busybox version 0.60.2.
Namely, they won't run in my custom board with powerpc processor (mpc8260).
This it what happens:

****************************************************************************
bash-2.03# busybox echo Moi!
Moi!
bash-2.03# busybox ash
Illegal instruction
bash-2.03# busybox msh


BusyBox v0.60.2 (2002.01.25-08:55+0000) Built-in shell (msh)
Enter 'help' for a list of built-in commands.

Illegal instruction
bash-2.03# busybox lash


BusyBox v0.60.2 (2002.01.25-08:55+0000) Built-in shell (lash)
Enter 'help' for a list of built-in commands.

/ #
****************************************************************************

As you can see, for example echo and lash work just fine.
I am using uClibc-0.9.8 and debian cross-development tools.

Can anybody tell me what I'm doing wrong?

Cheers,
Mikko

P.S. Here is some additional information that I got using strace:
